Research Center for Clean Energy and Power, Jiangsu and CAS is a provincial scientific research institution approved by the Office of Organization Establishment Commission of Jiangsu Province. It is responsible for the part construction of high-efficiency and low-carbon gas-fired steam turbine testing apparatus assigned to Jiangsu Province, which is a national key scientific infrastructure project whose impersonal entity is Institute of Engineering Thermophysics, CAS. In the construction, several small test beds required sufficient and stable steam support, so the Center purchased a set of high-efficiency and stable WNS series steam boiler from ZOZEN Boiler.
Jilin Longyuan Fertilizer Co., Ltd., founded in 2004, is one of the subsidiaries of Longyuan Group. At present, the company has two ammoniation-granulation compound fertilizer production lines with a total annual output of 500,000 tons, a blended fertilizer production line with an annual output of 300,000 tons, and a potash fertilizer production line with an annual output of 100,000 tons. These high-capacity production lines placed high requirements on the steam quantity and quality of the boiler equipment and also posed a huge challenge to the boiler operating costs, especially the fuel costs. According to the actual demands, ZOZEN customized a set of SZL series coal-fired chain grate steam boiler for Longyuan Fertilizer. This series of boiler has sufficient output, high combustion efficiency and wide fuel adaptability, which can fully meet the needs of Longyuan Fertilizer.
This time, by virtue of the low-NOx emission advantage of WNS series gas-fired steam boiler, ZOZEN successfully reached the cooperation with Jiangbei Pharmaceutical. Zhejiang Jiangbei Pharmaceutical Co., Ltd., established in 1993, is a national high-tech enterprise and science and technology enterprise in Zhejiang Province which mainly produces solid preparations, APIs and medical intermediates. The company has a good product group including 7 categories of APIs, medical intermediates and solid preparations that are cardiovascular, central nervous, digestive tract, antiviral, anti-infective, anticoagulant, and anti-osteoporosis drugs. At present, the company has become an important base for the production and export of cardiovascular and antiviral drugs in the world.
In the carton production process, the steam heating system plays an important role in increasing the temperature of cardboard. With the WNS series gas-fired steam boiler which is high-efficiency, energy-saving, safe and eco-friendly, ZOZEN Boiler has successfully reached the friendly and long-term cooperation with packaging enterprises such as Pacific Millennium Packaging Group and Shengxi Packaging, and has also accumulated abundant project experience. This time, ZOZEN and Chongqing Yongsheng Packaging Co., Ltd. reached the cooperation on the WNS series condensing steam boiler project to provide sufficient and stable steam heat source for the carton and printing production lines.
Ningxia Jiali Potato Industrial Co., Ltd. founded in 2010 is a leading enterprise in the potato production and processing industry in Xiji County, Ningxia Hui Autonomous Region. The company has formed the whole industry chain covering the breeding, planting, processing and selling of potatoes. It has three production lines with an annual capacity of 55,000 tons of potato starches and one production production with an annual capacity of 10,000 tons of potato powders. In order to improve the product quality, Jiali decided to introduce a set of high-efficiency coal-fired steam boiler and put forward high requirements for the boiler’s environmental protection performance. After an extensive market research, Jiali finally chose the eco-friendly SZL series coal-fired steam boiler produced by ZOZEN Boiler to meet the huge demands for heat in the production processes of potato starches such as dewatering, concentration and drying.
Founded in 2007, Jiangsu Ruisin Metal Products Technology Co., Ltd. mainly produces galvanized steel strip, cold and hot rolled steel strip, and other extended products such as galvanized steel tube, light steel dragon aggregate, cable armoring materials, galvanized steel C, etc., which are widely used in the fields of building materials, photovoltaics, building decoration and agricultural greenhouses. In 2019, Jiangsu Provincial Government introduced the policy to promote the transformation and upgrading of the iron and steel industry and steel enterprises were encouraged to conduct innovations on the manufacturing technology and upgrade the production equipment to realize the intelligent and green manufacturing. In order to actively respond to this policy, Ruisin introduced a set of eco-friendly WNS series three-pass gas-fired steam boiler from ZOZEN Boiler to satisfy the heating demands of the production line and achieve good energy-saving and emission-reduction effects.
Heilongjiang Changfeng Coking Co., Ltd., founded in 2014, mainly produces coke, tar, crude benzene and other chemical products. In the second half year of 2019, the company invested more than 60 million RMB to launch a 6 MW coal gas thermal power project which required a set of 45 tph gas-fired boiler and the 6 MW condensing steam turbine generator set. If the project is put into use, it is expected to generate 60 million kWh of electricity per year and form a heat supply network covering 300,000 square meters, which is a municipal-level key industrial project and is highly valued by the local government. However, this set of steam boiler with a rated pressure of 3.82 Mpa and a steam temperature of 450℃ is a kind of A-grade mid-temperature and mid-pressure boiler, which sets high requirements for boiler design and manufacture.
Emeishan Tonghui Pharmaceutical Co., Ltd., founded in 2002, is a modern pharmaceutical enterprise integrating scientific research, production and sales with workshops for freeze-dried powder injections, small-volume injections, and solid preparations. With the continuous expansion of the production scale, the company's old boiler equipment could not meet the heating demands of the pharmaceutical production line. Therefore, after a series of market investigation, Emeishan Tonghui Pharmaceutical decided to introduce a set of WNS series gas-fired steam boiler designed by ZOZEN Boiler.
